Great need seen in intersex sport There is a great need for do- educationa] activities, particu- larly fcr such. activities which, while not pitting girls against beys, will stimulate healmy competition requiring a maxi- mum output of energy. The game oC korfball meets this demand and offers, in add- ition, an excellent opportunity of intersex cooperatioc and ap- preciation which few other co- educational activ i t i e s can Since the first natkmal dem- onstration of korfball at die AAHPER convention in Seattle, many requests have been re- ceived for information on rules and equipment. Although Hie wicker baskets nre much to be preferred, homemade metal baskets pro- vide an adequate substitute. Ne- gotiation are in process to bam the baskets and standards manufactured in Die United States. BISTORT In the early 1900s Nico Broefc- huysen, a acbool teacher in Am- sterdam, The Netherlands, at- tended a summer workshop in Sweden. During the recesses men and women played togeth- er at a game called ringball, a simple basketball type game in which the aim was Co score by throwing a ball through a ring or hoop attached to the top of a pole about ten feet hiph. Broekhuyser. was particular- ly attracted by the fact that the game was a coeducational activity and introduced it to his P'jpils upon his return to Hol- lar.d. Gradually the game seem- eO to have no written rules, it soon became apparent that some standardization was need- ed. As a result Broekhuysen wrote bis own rules and regu- lations. In order to make tie scoring of field goals easier to judge, the ring was replaced by a basket (Du: and so korkfball received its name. First demonstrated in Am- sterdam 1902, the game soon became so popular that by 1903 Hie large number of korfball clubs resulted in the organization of the National Korfball Association to regu- late conference competition. OrigiwQly starting with al- most uuembeis, the Dutch Korfball Association now num- bers more than mem- bers (from a population of 11 million) who play in various divisions and classifications de- pending on ability and age. The first international expo- sure of korfball took place dur- ing me 1920 Olympic Games at Erussels. Belgium. The founda- tion of the Belgian Kbrfball As- sociation in 1921 was its imme- diate result. Since 1923 more than 50 contests have been held between the representative na- tional teams. In the years before World War Two korfball spread to such countries as Indonesia, Surinam, the Dutch West In- dies, and IsraeL In 1946 a party cf Dutch players and officials gave exbiiHtwm games through- out England, where korfball be- came popular willrin a rela- tively short time. Now, besides Uie regular div- ision and cup games, many Eng lish teams have an exchange program with Dutch, Belgian, and German teams. Since the Triangular Trophy Tourna- ment has provided competition for the national teams of Hol- land, Belgium, and England. To intensify international competition, the European Tro- phy Cup Tournament has been organized, In this tournament the win- ner and the runners up of the national division of Holland, Belgium, and England compete each year Cor the European World Series. Since the organ- ization of the International Korfball Federation korfball has continued its growth. Recent developments in Germany, Spain, and South Af- rica give hope that fcorfball may become a truly interaa- tibnal sport. NATURE OF GAME During the past TO years korf- bajl has changed from a pure- ly educational physical activ- ity to a highly competitive game. Despite this transform- ation it bar maintained some characteristics that distinguish it markedly from other compet- itive team sports. One of the most attractive features of korfball is that the game is played by teams com- posed of both men and women, whose combined efforts are re- sponsible for -the outcome of the contest Seventy yean ex- perience has proved that it is possible to compete in this fa- shion without lowering the qual- ity of the game (physical per- formance and technique) and without endangering the fem- ininity of the girls and women participate. In addition lo the heaHhfu] physical development which re- sults from such vigorous activ- ities as running, jumping, and throwing, the game offers an opportunity for social develop- ment and social activity as do few others. Although men and women play with each o4her as a team, f.nd against each other as a (earn, there is no direct phy- sical contest between men and women. Attempts to organize competition between all male or all female teams have failed Utus far. Co-operation between the men and women of one team is pro- moted by the organization of the field, players, and rules. Thus the possibility of domin- ation of the game by one sex ;3s minimized. The playing field, although much larger, resembles that of three court basketball. A backboard is situated at each end of the field. The ball K mowd around from court to court by passing; dribbling or similar procedures are illegal. The purpose is to score a backet, each of which results in the net pain of one point. As in most European games the scores never reach astronomi- cal proportions. Although the game is highly competitive, it gives evidence of a certain chivaJry in an unwritten but generally accepted rule of ptay- ing in the spirit of the rules than by the letter of the rules. Generally it is consider- ed bad taste and unsportsman- like lo take advantage of situ- ations that create unfair com- petition. So, for instance, a player re- frains from activity in a situa- tion where his opponent is tem- porarily unable to participate as result of an injury or faulty equipment. If a player is un- able to continue play, his op- ponent ffenerallv leaves the field until the di'sabled player has teen replaced. Although the game eocKirts of 45 minute periods, substi- tution for injured players is per- mitted only during half time. Tf a learn is imforbmate enough to n player during the sec- ond half of the game, it must proceed with 11 players rather than with its full complement.

Factors to consider Buying educational gifts By ROY MICHELSEN and JOHN BRAUN Junior Educational gifts or personal purchases appear to be a sound investment but particularly in the area of scientific equip- ment it is very easy to spend money unwisely. The remaind- er of this article deals with some factors to consider in the selection of microscopes and astronomical telescopes and binoculars. Magnification is not the only factor to consider with any of the three instruments. The ob- jective lens of each instrument is capable of separating a lim- ited amount of detail in the ori- ginal subject. Using high pow- er eyepieces will spread the image over a bigger area but they cannot reveal details which the objective lens does not pick up. Magnification which does not increase visible detail is known as empty mag- nification. The revolving power of a lens is its ability to reveal fine detail. Microscope objectives are de- scrbied by two numbers stamp- ed on the lens. One number is the power (e.g. 4x, lOx, 40x) and the other is the numerical aperture (e.g. .25, Lenses without both of these numbers cannot be trusted to give pood service. High nu- merical apertures indicate high resolving powers. The upper limit of useful total magnifica- tion (objective power x eye- piece power) is about 1000 x the numerical aperture. Don't expect any microscope under to give useful magnifica- tion higher than 650 x (i.e. 1000 x the .65 numercial aperture which is common on 40 x ob- jective 10 x and 15 x eyepieces are normally ade- quate for normal use. Low cost microscopes with zoom fea- tures should be avoided because of poor optical quality. Costs? It is possible to get useful student microscopes for about which have a smgle objective and only one eye- piece. Microscopes with more than one objective lens mount- ed on a turret can be obtained in the to bracket. Avoid kits. Most kits con- tain materials of little or no use (including the micro- Before getting any type of op- tical aid for astronomy you should become familiar with the motion of the stars and planets. When you feel more magnification is required 7 x 50 binoculars are a good start. 7 K 50 binoculars give a brighter image than any other binocu- lars commonly produced. The increased brightness is oiJy no- ticed when your eyes adjust themselves to low light condi- tions so that UK iris openings of your eyes are large enough to accept the full beams of light coming from the eye- pieces of the binoculars. Good binoculars can be used to observe the moon, star clus- ters, double stars, the Milky Way and some of the moons of Jupiter. A good pair will cost about but fairly good ones can be bought for less. If after a few months of use you are no longer interested in astron- omy you will still have a pair of binoculars for general use. If after this time you are 'still interested in astronomy it should be quite safe to advance to an astronomical telescope. A good fully assembled and equipped astronomical tele- scope wlil cost in excess of An equatorial mount is re- quired to facilitate the finding and tracking of celestial ob- jects. A very sturdy base is re- quired because the high mag- nification of the telescope wfll magnify all vibrations of the telescope tube. Unfortunately many telescopes in the to range are wen equipped mechanically but for cost rea- sons the optics involved are second rate. SECOND RATE The optics of a telescope are described first by the diameter of the objective tens and sec- ondly by their focal ratio or f number (focal length divided by Dollar for dollar reflecting telescope: are su- perior to refractive telescopes. A reflecting telescope is ca- pable of producing useful mag- nifications of about x for every inch of diameter cf the objective mirror. The magnifications produced can be varied by ucing differ- ent eyepieces. The inasniGca- tion is equal to tbe foca! length of the objettive lens divided by the focal terjrth of the eyepiece. Higher magnifications than 60 x per inch of oc-jedive diame- ter (for reflectors) gft into the zone of empty as well as dimmer images. Irrage briglitntss is inversely proportional lo lie square of the magnification. This would mean that on a partielar tele- scope the image formed at SO x uouW be 4 times x birght as the image found at 100 x. Consider nothing smatter than 3 inch diameter refractor of a 6 inch diameter reflector. This will allow you to see de- tails on mars, bands of Jupi- ter, Saturn's ring and other gal- axies to mention only a few items. It is possible to make jtar own reflecting telescope with savings of up to 80 per cent Advanced tebcnical knowledge is not rantired and alt of the parts, including time to make your own objective mirror, can be obtained locally. Several boots are available concerning the equipment indi- cated above. Those intended would be well advised to refer to them before buying or bouaV ing your own equipment Hope- fully a combination of these sources win help reduce the amount of uninformed buying and selling. Dietary service staff Preparing and serving food is an important hospital Cask and one which involves the combined efforts of individuals with a wide variety of braining. In addition to the positions illustrated here, the dietary ser- vice staff may include a chef, cooks, bakers, and a variety of assistants and supporting staff. The registered dietitian acts as a consultant to the physician, instructs patients requiring mo- dified diets, plans menus and diets, and manages the food services in larger mstitu'Jons. University education in diete- tics or home economics is re- quired. Hospitals also employ a die- tary technician as an to the professional dietitian. IB smaller hospitals, the techni- cian assumes a posi'ion of greiter responsibility. The two- year training program is based in the institute of technology.
